Abstract

This invention relates to a method for enzymatic treatment of proteinaceous fibres. According to the method protein fibre is contacted with an aqueous solution comprising tyrosinase enzyme under conditions suitable for the function of the enzyme. The tyrosinase enzyme may originate from various sources, such as from plant, animal or microbial origin. Proteinaceous fibre may comprise wool, wool fibre or animal hair or it may comprise silk, spidersilk or human hair.
